3.27.2.2.4 Configuring events
If the counter starts a new count loop, an event is output. Output QO of
function block
CTR outputs the signal. This signal is extended (FB PDF),
converted from the "boolean" format into the "word" format (FB B_W),
and transferred to function block
S7EMA as the first event message
word.
The S7EMA is assigned a virtual data block number for the user data
area "event messages" via a global operand (OP connection).
NOTE
The data block No., specified under SIMADYN D for the OP
connection, must also be assigned the configured area pointer for
event messages under ProTool/Lite.
